someone french(?) needed

i need someone who would be kind enough to find out for me (on some french site maybe) what is the cheapest way of getting from:

paris

to:

amsterdam.

date: 5th of april, don't care when.

not important if it's by plane or train, i'm just searching for the cheapest way.

thanks in advance!

edit:

as a side note, i checked skyeurope and some other cheap airlines, but only found flights that go via london and are around 150 euro.
there must be a cheaper alternative :(
